ANTl-SASH-RATTLING DEVICE.

SPECIFICATION forming part of Letters Patent No. 340,945, dated April27,1886.

Application filed December 6, 188-1. Serial No. 149,664. (No model.)

To all whom it may concern:

Be it known that I, GEORGE E. GORHAM, a citizen of the United States,residing at Albany, in the county of Albany and State of New York, haveinvented certain new and useful Improvements in Anti-Battling Dev cesfor Drop-Sashes, of which the following is a specification, referencebeing had to the accompanying drawings.

The object of my present invention is to obviate the annoyanceoccasioned to the traveling public by the incessant jarring and rattlingof the ordinary drop-sashes in general use for tramways, stages,omnibuses, and the like.

To this end my invention consists in the novel construction of parts setforth in the claim,forming a part of this specification.

Referring more particularly to the accompanying drawingsforming a partof this speci fication, and wherein like letters indicate like parts,Figure 1 represents in perspective and partly broken away a car-window,showing my invention in operative position. Fig. 2 represents inperspective an enlarged detail view of the latter. Fig. 3 is a rearelevation of the same. i

K indicates the exterior wall of the carbody, having suitable openingsfor the inseu tion of the frames F ofa series of windows, as P.

It indicates one of the window-separating partitions, extending inwardlyto the inner -car-wall, L, and having a facing-strip, N,

restingupon the upper border-piece, L, of said inner wall. Anintervening space separates thewalls K and L for the reception of thedrop sash and the screen or shutter M when the latter are lowered. Abead, H, forms, with the facingstrip N, a guide for the screen M, and aflanged projecting ledge, G, is provided for the lower cross-piece ofthe sash-frame. These several parts in the relationship shown anddescribed constitute an ordinary and wellknown construction of drop-sashwindow suitable for the application of my anti-rattling device. Thelatter consists of a base-plate, B, of cast-iron or other suitablematerial, perforated at A, and having a curved slot, D. Upon this plateis mounted, by means of a headed rivet, S, the

loosely-turning friction-roller O, of rubber or other like resilientmaterial.

As thus constructed the fixture is attached to the partition R primarilyby means of a screw passing through the perforation A,and is secured inplace by the screw E entering the slot D. The pressure of the rolleragainst the sash-frame F is attained by moving to ward the latter thelower end of the baseplate B, and fixing it then in position bytightening the screw E. The point of contact between the roller andsash-frame is to be chosen at or near the top cross-piece of the latterwhen the window is closed, as shown in Fig. 1.

As shown in Fig. 3, I prefer to make the base-plate B comparativelynarrow, pivoting the roller 0 eccentrically thereon, as illustrated. Bymeans of this arrangement ofparts the same fixture may be used to fit asash which runs close to the partingstrip,and one which has shrunkenaway a quarter or half inch therefrom, the fixture being located ateither the right or left hand of the sash, as the conditions mayrequire, and so attached to the parting-strip that the slot D shall beeither below the roller, as shown in Fig. 1, or above the same, theplate in the latter instance being in a reversed pos tion.

The mode of operation of the invention is suffieiently apparent fromwhat has been said above. In its closed position thewindowframe isforced firmly against the cavbody, and all rattling and jarring therebyprevented. The window is raised and lowered in the usual manner andwithout material interference by the fixture.

Should the rubber in course of time become worn by use, it is merelynecessary in order to render it as serviceable as before,to loosen theadjusting-screw E and move the lower end of the base-plate anappropriate distance inward.

\Vhat I claim, and desire to secure by Letters Patent, is-- Theanti-rattling device for drop-sashes, consisting of a base-plate havingthe perforation A, and slot D, with the pinion S, and loosely-turningfriction-roller O, of resilient material, the said roller being mountedupon I00 of in such a manner that it shall extend at in presence of twowitnesses. unequal distances from the opposite sides of the base-plate,thereby providing for unequal GORHAM' 5 distances between theparting-strip and the \Vitnesses:
